Casboult maybe? Levi has some grit about him.
He's showed that at times through the years but not quite as consistently as he has been doing now.
If someone is going to be doing any battering, I'll take the chance on it being Levi right now.
A combo of big Kreuz and Cas in the ruck should be able to work Aliir over physically. He doesn't have any proper ruck support and doesn't even normally play ruck himself.
Should be a focus of the rucks this week. Could give us a real advantage out of the middle and at the contest.
